exec ('rsync ...') fails

nemonoman

In Linux, Logged on as root.

cd /home/ad2adn2/domains/ad2adnetwork.biz/public_html/cron
rsync -ravn /root/BIZ/rsynctest /root/BIZ/thisworks/

works. Output:
[INDENT]building file list ... done
created directory /root/BIZ/thisworks
rsynctest/
rsynctest/cron.php[/INDENT]
crontest.php in that same directory:

echo exec ('/usr/bin/whoami');
echo "<BR>";
echo exec ('pwd');
echo "<BR>";
echo exec('rsync -rav /root/BIZ/rsynctest /root/BIZ/thisworks/');

Fails. Output:

Does NOT create testdirectory or copyfiles
Fails even if testdirectory exists with chmod 777

Help?

Do both the 'root' and 'BIZ' directories have read and execute permission for all? (I'm just thinking that each directory in the tree has to have at least read and execute for the apache user to see the lower-level target directories below it that you want to work on.)

I thought I had permissions correctly set for the directories in question, but I went back and did chmod 777 and voila.

HOWEVER...

What I was REALLY trying to do was to rsync database files stored in /var/lib/mysql. This, of course is way above the apache directory level. And this fails.

I have tried making a UNIX script to do this, and then using exec to run the script. The script outputs a string that shows it has run, but the files have not been rsynced.

I went through and chmod 777'd all the way down the directory tree, and still have had no luck.

At this point, I don't get it.

As root I have tried to su apache (as the whoami response to myscript says 'apache'). However the response is:

su apache
This account is currently not available.

Huh??
